' Application January 2a, 1938, Serial No. 187,518 In France January li,1938 3 Claims. (cl. 189-34) The present invention relates to walls,partltions, and other similar building elements which will behereinafter referred to by thegeneric name of walls.

The chief object of the present invention is to provide a wall which isstrong, light, incombusti-1 ble, heat insulating, sound insulating, andcheap to erect, and the construction of which permits of eliminatingeventually, or at least reducing to a considerable extent the skeletonor framework which, up to this time, had tobe made in advance, whiledispensing, for the assembly of the wall elements, with the bindersusually employed for the construction of walls, such as cement andplaster.

According to an essential feature of the present invention, thecomposite wall includes at least one metal sheet, smooth, corrugated orribbed, which constitutes the external or internal facing of the walland, at the same time, eventually, the framework or skeleton thereof,and a light and insulating pugging. I This pugging may be glued orflxed'in any other suitable manner to said metal sheet or it may be heldat a distance therefrom in such manner as to leave between them aninsulating layer of air.

- According to another feature of the present invention, this pluggingconsists of at least one layer of a fabric shaped in such manner as tohave a high moment of inertia and made rigid by impregnation or coatingwith an incombiistible plastic composition of matter, such as cement,plaster, a .paste chiefly composed of refractory materials, and so on. v

On the side opposed to the metal sheet, the pugging may be fitted eitherwith a second metal sheet, which may or not have a carrying action, orwith a coating of any suitable material, preferably one havinginsulating properties.

According to a particularly advantageous embodiment of the presentinvention, the metallic face or faces of the wall is, or are, made ofpanels made and assembled in .the manner described in the prior U. 8;Patent application Ser. No. 63,952, filed February 14, 1936, now PatentNo. 2,164,681,

granted July 4, 1939.

Other features of the present invention will result from the followingdetailed description of j some specific embodiments thereof.

Preferred embodiments of the present invention will be hereinafterdescribed, with reference .to the accompanying drawing, given merely byway of example, and in which:

Fig. 1 is a .partialver-tioal section of an emthe present invention;

bodiment of a composite wall made according to Fig. 2 is a similar viewof another embodiment of the invention.

by walls of buildings, .thes'e stresses being generally those ofconcussion or lateral pressure accidental-1y applied to the wall byfurniture or persons, and constituting the ordinary hazards of ahabitable structure.

c. A plate 3 of an insulating material, for instance wood pulp, formingthe internal facing of the wall. I

These varioim elements are assembled together by .gluing, for instanceby means of a special glue of a known type, consisting chiefly of analkaline silicate and magnesium carbonate, with lthe addi-' tion ofglass powder and fibers of asbestos, or by.

The wall shown by Fig.1 includes the followin means of a glue consistingchiefly of casein and lime.

In a wall made as above described, the only element which supportsstructural stresses and loads is the metal sheet facing l. The flooringsare secured to this element of ,the wall, for instance by means of angleirons or other sectional irons.

In theembodiment shown by Fig. 2, the wall includes the same elements asabove described. But

inthis case the pugging 2, which is for instance analogous to thatdescribed-with reference to Fig. 1, is held apart from the carryingfacing l, in such manner as to leave a layer of air between saidprofiled irons, or transversal holding members may be secured both tothe pugging and to the metal facing l by any suitable means, such asglueing or the like.

Wall elements constituted as disclosed may be preformed and assembled insitu through mutual interengagement so as to form a rigid whole withoutany complementary frame being required.

- In a general manner, while I have, in the above description, disclosedwhat I deem to be practical and em'cient embodiments of the presentinvention, it should be well understood that I do not wish to be limitedthereto as there might be changes made in the arrangement, disposition,

- and form of the without departing from the principle of the presentinvention as comprehended within the scope of the appended claims.

What I claim is:

1. A thick hollow unitary prefabricated soundproof wall-formingassembly, consisting of a single self-supporting sheet metal paneladapted to carry the structural load imparted to the wall, and a thickrigid cellular lining structure made of relatively stifl light-weightnon-metallic insulating material, said structure comprising anundulating framework secured to said metal panel, and a facing panelformed of similar stifl! light-weight non-metallic material and securedto said framework at the side thereof remote from the metal sheet,-saidlining structure adapted to withstand local stresses ordinarily impartedto a wall in the usual building construction.

2. A thick hollow \mitary prefabricated soundproof wall-formingassembly, consisting of a selfsupporting sheet metal panel adapted tocarry the structural load imparted to the wall, and a thick rigidcellular lining structure made of relatively stiff light-weightnon-metallic insulating mate rial, said structure comprising anundulating framework, means for securing said framework 4 in spacedrelation to said metal panel, and a ,work at the side thereof remotefrom the metal sheet. said lining structure adapted to withstand localstresses ordinarily imparted to a wall in the usual buildingconstruction.

3. A thick hollow unitaryprefabricated soundproof wall-forming assembly,consisting of a selfsupporting sheet metal panel adapted to carry thestructural load imparted to .the wall, and a thick rigid cellular liningstructure comprising a framework composed of a sheet of stifflightweight insulating material made of fabric impregnated with ahardened plastic material and disposed in an undulating or zigzagarrangement and securedto said metal panel, said framework being of suchrigidity as to withstand local stresses to which the surface of the wallof a building is normally subjected but insufficient to support thestructure, and a facing element secured to said framework to provide asuitable finish for the wall surface on the side opposite the
